Abstract
The invention relates to a wide-angle lighting solar energy photovoltaic cell which is formed by assembling a full transparent upper cover, a silicon solar cell, a lower bottom plate and the like, wherein the full transparent upper cover on the silicon solar cell is or covered with full transparent mutually parallel cylindrical wide-angle lenses and spherical grid wide-angle lenses. The visual angle of the cylindrical wide-angle lenses or the spherical grid wide-angle lenses is 90 degrees-135 degrees. The wide-angle lighting solar energy photovoltaic cell can absorb sunlight to the maximum extent without rotating a solar panel in the whole day from sunrise to sunset under the situation of fixing the solar panel, be always in the state with the maximum conversion rate and improve the power by about 20%. The structure is simple, and a panel of an upper cover plate does not need to be increased, thereby realizing very low using cost, improving the efficiency and being greatly conductive to popularization of the silicon solar cell.
Description
technical field [0001] The invention relates to new energy, in particular to a solar photovoltaic cell. Background technique [0002] Solar photovoltaic power generation is a new and renewable energy source. It is the most promising new energy technology in the world. The energy converter of solar photovoltaic power generation is a solar cell, also known as a photovoltaic cell. The principle of solar cell power generation is the photovoltaic effect. When sunlight (or other light) shines on a solar cell, the cell absorbs light energy and generates photoelectrons-hole pairs. Under the action of the built-in electric field of the battery, the light energy of the sun directly becomes practical electrical energy. A solar cell is the smallest unit of photoelectric conversion. After the solar cells are connected in series and parallel and packaged, they become a solar cell module. The solar cell modules are then connected in series and parallel and installed on the bracket to ...
